Chronic Kidney Disease

Last Modified 22/11/2023 14:47:13 Share this page


Chronic kidney disease occurs when a person suffers from gradual and usually permanent loss of kidney function over time. This happens slowly, usually months to years. With loss of kidney function, there is an accumulation of water, waste, and toxic substances in the body, which are normally excreted by the kidney. Loss of kidney function also causes other problems such as anaemia, high blood pressure, acidosis (excessive acidity of body fluids), disorders of cholesterol and fatty acids, and bone disease.

Facts and figures

Prevalence of chronic kidney disease

For further information regarding the source of the Quality and Outcomes Framework (QOF) prevalence data and its limitations please see the note on QOF Data.

In 2021/22, 8,534 people (aged 18 and over) in the Blackpool ICB sub-location (formerly NHS Blackpool CCG) were identified as living with chronic kidney disease (CKD).1 This equates to 6.0%, which is significantly higher than England's average (4.0%), although the value has reduced slightly from 6.2% in 2020/21.

Blackpool's sub-location is shown as a purple marker in figure 1, with all other sub-locations across England shown in blue. Blackpool's CKD prevalence is among the top 10 of highest rates in England.

Figure 2 shows all the GP practices that make up Blackpool's sub-location (formerly NHS Blackpool CCG). There is a considerable range in recorded prevalence of chronic kidney disease at GP practices from 4.0% to 7.9%. Eight practices have a patient prevalence rate of less than 6%, whilst eight have a rate over 6%.

The light blue practices in the funnel plot above have a significantly higher prevalence of CKD, compared to England. The three practices with similar prevalence of asthma (in yellow) are Adelaide Street Surgery, South King Street Medical Centre and St Paul's Medical Centre.

Risk factors

Kidney disease is most often caused by other conditions that put a strain on the kidneys.

High blood pressure (hypertension) and diabetes are the most common causes of kidney disease. The evidence indicates that high blood pressure causes just over a quarter of all cases of kidney failure. Diabetes has been established as the cause of around a quarter of all cases.2
